Predictable exploration
Search, filters, and deterministic pagination make a large dataset navigable without unexplained result reordering.
The nutrition score is an experimental, unvalidated heuristic. DataNutri is an informational tool, not medical advice.

Context
What needed to change.
Nutrition datasets are extensive, full of missing values, and difficult to compare. The challenge was to enable fast investigation without turning absence into zero, oversimplifying the source, or presenting an experimental metric as clinical truth.
The solution provides search, filters, and deterministic pagination; server-rendered food pages; nutrient comparison; similarity ranking; portion calculations; and CSV export. The application queries a read-only replica and keeps the original data accessible.
The delivery
A system designed end to end.
Nutrition comparison
Foods can be compared by nutrients, portion, and similarity, with missing values and zero treated as different states.
Calculation and export
Users adjust portion size, recalculate values, and export relevant slices to CSV.
Source transparency
The USDA origin remains explicit and the experimental score is shown with clear limits and no clinical claim.
